Unless your DH opted to "waive" the resort fee (which is pretty difficult to do), he is entitled to the list of benefits posted by Miffy. Of course, If he made LONG DISTANCE calls, this would be a different matter entirely. Perhaps the phone number he used to call you on your cell phone is long distance.
All the phone rates are CLEARLY listed on the convenient pad clearly located next to the phone. Long Distance charges are not controlled by the Dolphin, but by the carrier they use. The charges are standard in the Hotel industry, and will be assessed everytime you use a hotel phone for a LONG DISTANCE call.
It was very nice of the Dolphin associate to reduce the charges to less than $100. Some Hotel properties will refuse to assist the patron in such a matter, and you will be forced to either contact the phone company directly, or dispute the charge on your credit card. I'm sure your DH has learned a very valuable lesson, and will not use a hotel phone for any long distance calls in the future. I use the phone for long distance calls, but only to connect to the CALLING CARD toll-free number! I also use the internet connection...which is the price of a local call at the Dolphin for the first 59 minutes. You must disconnect and reconnect to prevent the "over 60 minutes" fees from being assessed.
